According to the Maryland Emergency Management Agency, 25 state troopers and four Baltimore City employees will be following 23 emergency workers from around the state who previously left for northern New Jersey.

"As we were preparing for Hurricane Sandy, several other states came to Maryland with personnel and equipment to help with water rescues and operating emergency operations centers," Gov. Martin O'Malley said in a prepared statement. "We are thankful that we are now able to return the favor in states to our north, which suffered more damage from Sandy."

The troopers are leaving Sunday for Fort Dix in central New Jersey, where they will help local law enforcement officers, mostly in Monmouth and Ocean counties. The Baltimore City employees, led by Robert Maloney of Mayor Stephanie Rawlings-Blake's Office of Emergency Management and Public Safety, are heading Monday to Albany, N.Y., where they will work with employees in the New York State Emergency Operations Center.

According to MEMA, 10 two-person advanced life-support ambulances and three supervisors from Maryland went to New Jersey on Thursday. They started at the Atlantic County Training Center near Atlantic City and were later sent to MetLife Stadium in northern New Jersey and other sites in Jersey City, N.J. The team includes units from a private service, Life Star, and public safety units from Baltimore City and Talbot and Washington counties.

Edward McDonough, public information officer for MEMA, said the public employees will be deployed for as long as they are needed. He said government agencies in Maryland have an understanding with other states that calls for them to be reimbursed by the Federal Emergency Management Association for sending employees on an open-ended basis.
